octeontx2-af: Remove redundant initialization of pointer pfvf

The pointer pfvf is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
Fixes: 56bcef52 ("octeontx2-af: Use npc_install_flow API for promisc and broadcast entries")
